LOCK-JOINT FOR TABLE-FRAMES.

To all 1c]: am it may concern:

Be it known that I, Jonx l ons'rnn, acitizen of the United States. residing at- Los .-\ngeles, .in the county of Los Angeles and State of California. have invented new and useful Improvements in Lock-Joints for Table-Frames, of which the following is a specification.

My object is to make a lock joint for table frames and the like, and my invention consists of the novel features herein shown, described and claimed.

Specifically my object is to make knockdown tables and the like having lock joints by which the tables may be readily set up and knocked. down without the use of nails, screws, bolts and the like. i

Figure 1 is a perspective of a square table having lock joints by which it may be set up or knocked down in accordance with the principles of my invention.

Fig. 2 is a perspective of the top removed from the table.

:Fig. 3 is a fragmentary perspective of the frame, parts being disconnected and ready to go together.

Fig, 1 is a perspective of a round table having my lock joints.

rig. 5 is a perspective from the bottom of the table top shown in Fig. 4.

Fig. 6 is a perspective of the pedestal employed in the table shown in Fig. 4=.

Fig. 7 is a perspective of the two crossed pieces forming the. base for supporting the pedestal the pieces being disconnected.

Fig. 8 is a fragmentary bottom plan as seen looking in the direction indicated by the arrow 8 in Fig. 3.

Fig, 9 is a fragmentary bottom plan as seen looking in the direction indicated by the arrow 9 in Fig. 4.

Referring to Figs. 1, 2 and 3, the legs 1 are straight posts rectangular in cross section and have slots 2 and 3 cut crosswise of each other from their upper ends. The crosspieces 4 have slots 5 cut from their upper edges substantially half way across the width, and recesses 5 extending the remaining distance across the width and extending from the outer face substantially one-third of the distance across the thicknesses. The side pieces 6 have slots 7 cut from their lower edges. The crosspieces 4 have necks 8 fitting in the slots 7 and the side pieces 6 have necks 9 fitting in the slots 5. In assembling the parts thus constructed the cross- Specification of Letters Patent.

pieces 4 may be placed in the slots 3 and the sid pieces (3 may be placed in the slots 2 and the frame is complete.

The slots 5 are wide enough to receive, the thickness of the side pieces 6 while the slots 7 are only wide enough to receive the necks 8 formed by making the. recesses 5. The object of the recesses 5 is to protect the pieces 6*. As shown in Fig. 8, the inner .end of the piece 6* fits in the recess 5 to hold the piece (3 from moving laterally and splitting as might occur when the lower edge of the piece (i receives a blow from either side. The table top 10 fits loosely upon the frame. If desired the parts may be glued or otherwise permanently connected.

. The knock-down table thus constructed may be made in a mill and the parts packed in bundles for shipment, and when desired the parts may be readily assembled by unskilled persons, and such tables may be set up for temporary use as-at' picnics, public assemblies and so on, and when the use is ended the tables may be readily knocked down and packed for reshipment.

Referring to the modification shown in Figs. 4, 5, 6 and'7, the base piece 11 has a straight lower face 12 adapted to rest upon a floor and a notch 13 cut down from its face at the longitudinal center, and the re-. cesses 13 and 13 extending downwardly from the notch 13, said recesses 13 and 13 being cut from the side faces substantially one-quarter of the thickness of the piece 11. The base piece 14 has a straight lower face 15 and a notch 16 cut upwardly from its lower face at the longitudinal center. The base piece 11 has a neck 17 formed by the recesses 13 and 13 and fitting in the notch 16, and the base piece 14 has a neck 18 fitting in the notch 13, so that when the pieces 11 and 14 are assembled they are crossed at right angles and the faces 12 and 15 are level to fit upon the floor.

The object of the recesses 13 and 13 is to protect the portions 18 and 18 from being split by a blow upon either side. The end faces of the portions 18 and 18 fit in the recesses 13 and 13 as shown in Fig. 9, and obviously the lower faces of the portions are braced laterally.

The pedestal 19 is preferably a straight heavy stick eight sided in cross section and crossed notches 20 and 21 are formed from one end of the neck, and similar crossed notches 22 and 23 are formed from the other end of the neck. The end faces 24 and 25 of the neck are flat and at right angles to the side faces.

After the pieces 11 and 14 have been fitted together the pedestal 19 may be inserted downwardly with the crossed pieces 11. and l-lfitting in the crossed slots of one end of the pedestal so as to lock the parts together and hold the pedestal upright.

.The circular table top 26' has crossed pieces 27 and 28' extending downwardly from its lower face and after thepedestal 19 has been mounted upright the top 26 may be placed in position with the crossed pieces 27 and 28 fittin in the crossed notches of the upper end 0 the pedestal and the table is complete and ready for use.

If the table is to be used only temporarily no fastening means is required and when the temporary means is ended the parts may be readily separated and packed for shipment. If the table is to be permanently set up the parts may be glued, nailed or otherwise fastened permanently together."

Thus I have produced a lock joint construction for table frames and the like comprising crossed sticks notched into each other to be on the same level, one stick 'being recessed to receive the end face of the weak portion of the other stick, and a supclaimed.

, I claim: Ya

v1. In a lock joint frames comprising a'rectangular frame having side members crossing at the ends and notched into each other to be on the same level and a leg member for each corner of the frame notched downwardly from the top crosswise in such a manner as to form four rectangular members adapted to fit closely to the cross formed by the-side. members at each corner of the frame.

'2. In a lock joint construction for table frames comprising a rectangular frame hav mg side members crossing at the ends, each side member being notched half way and recessed the remaining distance at the point of crossing so that the side members may be fitted to each other on the same level and legs for the corners of the frame notched downwardly from the top to form four upstanding members adapted to be fitted over the cross at each corner of the frame. In testimony, whereof I have signed my name to this specification.
